Question description

A two-stage rocket moves in space at a constant velocity of 4540 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1310-kg upper stage is 5660 m/s. What is the velocity (magnitude and direction) of the 2260-kg lower stage immediately after the explosion?
